When it comes to markets, the first deadly sin is greed, says the author of The Blind Side and Moneyball. Here he conducts a tour through five of the most violent and costly upheavals in recent financial history, illuminating how the underpricing of risk leads to catastrophe. With anecdotal humor, Michael Lewis paints the mood and market factors leading up to each event, looks at contemporary accounts to explain what people thought was happening at the time, and analyzes what actually happened and what we should have learned from experience.
